Binding of F-spondin to amyloid-β precursor protein: A candidate amyloid-β precursor protein ligand that modulates amyloid-β precursor protein cleavage [PDF]

Proceedings of the National Academy of Sciences, 2004
Amyloid-β precursor protein (APP), a type I membrane protein, is physiologically processed by α- or β-secretases that cleave APP N-terminal to the transmembrane region. Extracellular α-/β-cleavage of APP generates a large secreted N-terminal fragment, and a smaller cellular C-terminal fragment.

Strategies to Improve the Lipophilicity of Hydrophilic Macromolecular Drugs

Advanced Healthcare Materials, EarlyView.
Hydrophilic macromolecular drugs can be successfully lipidized by covalent attachment of lipids, by hydrophobic ion pairing with negatively or positively charged surfactants, and by dry or wet reverse micelle formation. Lipophilicity enhancement of hydrophilic macromolecules has several benefits including stability and bioavailability improvement ...

Cleavage of Amyloid-β Precursor Protein and Amyloid-β Precursor-like Protein by BACE 1 [PDF]

Journal of Biological Chemistry, 2004
Site-specific proteolysis of the amyloid-beta precursor protein (APP) by BACE 1 and gamma-secretase, a central event in Alzheimer disease, releases a large secreted extracellular fragment (called APP(S)), peptides of 40-43 residues derived from extracellular and transmembrane sequences (Abeta), and a short intracellular fragment (APP intracellular ...

Nanophotonic Strategies for Chiral Biosensing: Nanoparticles, Metasurfaces, Magneto‐Optical, and Quantum Approaches

Advanced Photonics Research, EarlyView.
Recent advances in nanophotonics‐based chiral biosensing approaches are comprehensively reviewed, highlighting key trends, advantages, and limitations of each technology. Special attention is given to emerging strategies that exploit magneto‐optical and quantum plasmonic phenomena to enhance sensitivity down to the level of a few molecules, or even a ...

Controlled cortical impact traumatic brain injury in 3xTg-AD mice causes acute intra-axonal amyloid-β accumulation and independently accelerates the development of tau abnormalities [PDF]

, 2011
Alzheimer\u27s disease (AD) is a neurodegenerative disorder characterized pathologically by progressive neuronal loss, extracellular plaques containing the amyloid-β (Aβ) peptides, and neurofibrillary tangles composed of hyperphosphorylated tau proteins.

Neddylation Targets and Stabilizes NLRP3 to Augment Inflammasome‐Mediated Colitis and Mood Disorder

Advanced Science, EarlyView.
NLRP3 inflammasome contributes to colitis and mood disorder. This study demonstrates that neddylation targets NLRP3 at K287, which hinders its interaction with K48‐linked ubiquitination E3 Trim31 and thereby stabilizes it. Neddylation blockade in myeloid cells and microglia mitigates DSS‐induced colitis and psychological stress‐induced anxiety‐like ...

HRS Degradation‐Induced Nicotinamide Deficiency in Placental Extracellular Vesicles Triggers Preeclampsia by Disrupting Maternal‐Fetal Immune Homeostasis

Advanced Science, EarlyView.
This study shows that lower NAM levels in PE‐derived pEVs correlate with disease severity. NAM‐deficient pEVs reduce Th1 and Th17 inhibition, leading to PE‐like symptoms. NAM in pEVs inhibits Th1 via SIRT1 and Th17 via macrophages. Reduced NAM in PE‐EVs is due to decreased HRS expression in trophoblasts, resulting from elevated HSP27.

Tetramethylpyrazine Nitrone (TBN) Reduces Amyloid β Deposition in Alzheimer’s Disease Models by Modulating APP Expression, BACE1 Activity, and Autophagy Pathways

Pharmaceuticals
Alzheimer’s disease (AD) is a neurodegenerative disorder associated with age. A wealth of evidence indicates that the amyloid β (Aβ) aggregates result from dyshomeostasis between Aβ production and clearance, which plays a pivotal role in the pathogenesis
